YouTube - my slightly modded '94.5 7.3 powerstroke

had a guy comment on this video saying it sounds like it's missing on an injector... i'm not too sure, so can you guys listen and throw in your two cents???

 

what are your mods?

 

it does sound off to me, Even at cranking it sounds odd. It dont sound smooth when you rev it either.

 

Yeah. I would look into that. It doesn't sound right.

 

6637 intake and 3" downpipe. In this video, the downpipe was the only exhaust I had at all.

 

Yup, injector missing, and weak battery and/or weak starter. That thing should light right off 1-2-3.

 

Look on the bright side, if an injector's bad, then it looks like it's time for Stage 1's.

 

Is that the onything that can cause it to miss?

 

I'm certainly no expert, but I would imagine that any number of things could cause an injector to miss.

 

I'm no expert either but i did just go through this on my truck. what I had going on was... I had two UVCH plugs burnt up. I bought the doorman repair kits from Orielys auto and spliced, soldered the new plugs on. It was also a good time to do injector o rings and glow plugs so i did those as well. the whole thing was around 300 bucks. the UVCH repair kits were about 62 bucks a piece and come with the gasket and the plugs. It seems like this is a pretty common problem. Although when my cousins truck was missing it was a bad injector so its probably one of those issues.

 

Hmmm....sounds very familiar. f350rebel7788's has a bit longer and slower cranking time, but once running it sounds JUST like mine. So much so in fact that my kid heard the video and thought my wife was home with the pickup!

What in the sound of it (once running) makes it seem to you guys like there is a weak injector? Are there any videos / wav files of a "right" running 7.3 to compare it to????

 

Here's a crappy video of mine to compare if you like, just click on it

 

what he said x2... darin, i can't really tell the difference between mine and yours...

 

ill upload a link to mine running im waiting for youtube to process the video
